Filter manufacturers have been using industry-recognized terminology as a way of communicating information relevant to filters. This is to help them discern the difference between filters and its components, along with its particular capabilities. All these terms are vital in understanding the characteristics of a particular filter, regardless of its brand.
Abrasives and Abrasion
Abrasives are particles that “abrades” or wears moving surfaces, resulting in abrasion. Dirt, grit, or metallic particles often cause abrasion, or the rubbing away or grinding of two surfaces due to friction.
Cavitation Corrosion or Erosion
Once an engine is subjected to intense vibrations or a sudden pressure drop, voids or air bubbles tend to form. When these voids or air bubbles collapse, the shock waves often cause severe mechanical damage to metal surfaces.
This kind of corrosion happens when two different metals that are in contact with each other in a liquid results in an ion exchange. Since one metal gives off to another, the metal wears away or degrades.
Fuel combustion often generates sulfur. Once this comes in contact with water, sulfur becomes acidic, then gradually corrodes the metal engine parts.
Perhaps the most dangerous form of corrosion is when the engine experiences a localized attack, wherein the depth of penetration is the same order as the diameter of the area that was corroded.
